Give them enough money every month to cover the negative cashflow due to their nursing home bill.  

@Shema Cochrane Ty covered a lot of it.

If you sell your only overachiever to go with a more leveraged position, you could have 2-3 properties that may cover themselves or even provide a little profit, but when the rental markets shift (and they do), now you have 2-3 properties that all require you to supplement for their shortages. 

Moving there initially since low down then ideally want to rent some rooms to cover mortgage!

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

How to Structure the Deal to Protect Your $20KIf you’re willing to cover the $20K arrears, here’s how to protect yourself:Option 1: Secure Your Funds with a Lien or Escrow AgreementUse an escrow account: Deposit the $20K into escrow with clear terms—if the assumption is denied, the funds return to you.Record a promissory note & lien: If the deal falls through, this would give you a legal claim against the property to recover your funds.Option 2: Sub-To + Wrap While You AssumeSubject-to deal: Take over the existing loan payments before assumption approval, securing control.Escrowed deed transfer: The seller signs the deed into escrow only to be recorded after assumption approval, ensuring they can’t back out.Lease option fallback: If the assumption is denied, consider a lease option agreement until another solution is found.Option 3: Negotiate a Seller Financing HybridAsk the seller to carry a small second note for the $60K equity gap at favorable terms.Use your $20K as a down payment, structured as a secured loan against the property.3.

I'd recommend looking at costs. your build cost is going to be well over other homes because of the fixed costs like slab, Hvac, roof, etc. check the market drivers and weight the benefits of short term versus long term. long term is no furniture and help pays mortgage but at this size it doesn't really cover everything. we didn't find a lot of economies of scale in single family detached. can you build more than one unit?

The plan was to utilize the HELOC as the down payment then getting a conventional loan to cover the remaining 80%.

The first thing the technician did was take a toilet tank cover off and run his hand across the bottom.

Ultimately build equity by having tenants cover mortgage.
